A stalactite (UK: / ˈ s t æ l ə k ˌ t aɪ t /, US: / s t ə ˈ l æ k t aɪ t /; from Ancient Greek σταλακτός (stalaktós) 'dripping', from σταλάσσειν (stalássein) 'to drip') [1] is a mineral formation that hangs from the ceiling of caves, hot springs, or man-made structures such as ...
Broomstick stalagmites are very tall and spindly; Totem pole stalagmites are also tall and shaped like their namesakes; Fried egg stalagmites are small, typically wider than they are tall; Stalagnate results when stalactites and stalagmites meet or when stalactites reach the floor of the cave; Flowstone is sheet like and found on cave floors ...

Stalagmites or flowstone may form where the water drops hit the cave floor. Soda straws are some of the most fragile of speleothems. Like helictites, they can be easily crushed or broken by the slightest touch. Because of this, soda straws are rarely seen within arm's reach in show caves or others with unrestricted access.
Cave labeled with the six most common types of speleothems: flowstone, columns, drapery, stalagmites, stalactites and straws. A speleothem is a geological formation by mineral deposits that accumulate over time in natural caves. [4] Speleothems most commonly form in calcareous caves due to carbonate dissolution reactions. They can take a ...
Luray Caverns, previously Luray Cave, is a cave just west of Luray, Virginia, United States, which has drawn many visitors since its discovery in 1878.The cavern system is adorned with speleothems such as columns, mud flows, stalactites, stalagmites, flowstone, and mirrored pools.
Rimstone dams form where there is some gradient, and hence flow, over the edge of a pool.Crystallization begins to occur at the air/water/rock interface. The turbulence caused by flow over the edge of the building dam may contribute to the outgassing or loss of carbon dioxide from water, and result in precipitation of mineral on this edge.
